T0 all wtom it may concern Beit known that I, EDWIN F. BEUGLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State'of New York, have invented new and useful Improvements in Machines for Preparing Barrel-Shells to Receive Heads, of which the following is a specification. A v

rlhis invention relates to a machine for crozing, howeling, chamfering and trimming the ends of the staves and also the ridges between the howels and chamfer's of the staves after the same have been assembled to form thehodv or shell of the barrel andbefore applying the final hoops and heads thereto. y i

rihe object of this invention is to provide a machine for performir'lg these functions accurately, eiiici'ently andexpeditiouslv with a minimum expenditure of labor and power.

In the accompanying drawings: i Figure 1 is a front elevation of a machine embodying mv improvements and showing the parts in their inoperative position. Fig. 2 is a topplan view of the same. partly in section. Fig. 3 is an elevation of the machine vien'ied from the left hand end thereof.

Fig. l. Figlo is a fragmentary longitudi= nal section showing the manner in which a dog of the chuck vring engages with a hoop of lthe barrel shell. n

Similar characters of reference indicate corresponding. parts throughout the several views.

Referring toFig. 14, 1 represents a barrel stave upon' which the various operations have been performed by the machine embodying my invention so-that when the stave is completed the same is provided with transverse Crozes Qvon its inner side near opposite ends thereof, howels at-the corners of the Crozes, ohamfers or beveis 4 between the croZes and the ends of the staves, end faces 5` at the outer ends of the chamfers, and ridge faces 6 between the chamfers and the howels.

Vhile the barrel staves are assembled in the form of a shell or bodv the same' are temporarilv held in vposition relatively to each other bv means ofptempor'arv hoops 7, preferably ofoiron while the operations of crozing, howeling, chamfering, trimming or Vfacing the ridgesvand ends ofthe s tav'es are being performed in the machine, which tem-i porarv hoops .engage with the peripherv vof the shell near its ends and are afterward replaced with permanent hoops or bands in the usual and well known manner. l

8 represents the lmain frame of the maohiii'e which may' be of any suitable construction to support the different working parts of the machine. i i

9, lOlreprese'nt two vhead stocks of suhstantiallvcircular or' ring-shaped form arranged transverselv and ina'n upright positionkabove opposite ends ofthe main frame so that they are iii axial armement ieiigtii-Y wise of the machine., On the inner side Aof each of the head stocks the same is provided with an internal annular" guide Igroove which receives a rotatable, chuck ring 12 adapted to encircle one end of the assembled shell or body of the barrer oii the periphery thereof and engage 'iriotioiiaiiv therewith. so that upon rotating thisy ringthe barrel she-11 wilil'be turned about a horizontal airis.4

hi order to stipt-lement' the triotionai enl @agement of the chuck rings' with the barrel body' by" a positive connection between the sain-e and ths shell oit-body so as to insure on the inner side of each chuck ring prefer-y ably on diametrically opposite sides thereof and each provided with a beveled sharpened edge 14: which is adapted'to engage by a slight cutting action with the outer sideV4 of the adjacent temporary hoop, as shown in Fig. 16 and cause the shell to turn with the respective chuck ring. In order to enable each dog to adapt itself to the particuv lar'part of the .temporary barrel hoop with which it engages and thus'permit of slight Yvariations in the .relation of these parts without affecting the operation'of the machine each of these dogs is yieldingly supported. The preferred means for this purpose,y shown in Figs. 5 andv 6, comprise a rocl lever pivoted on the chuck ring to turn vertically and carrying the respective chuck dog on its'v front arm, a spring arm 1 6 mounted on the adjacent part of the chuck ring andfenga-ging its free end with the rear yarm vof the respective dog lever, a tenlsion bolt orl rod 17 passing through the overlapping rear arm of the dog lever and the companion spring arm and connected with said arm of the dog lever, and a coil spring 18 surrounding the tension bolt or rod` and bearing at its outer end against the inner side of the spring'arm while its inner f end bears against a nut or shoulder on the innerv end of the tension bolt or rod. The

resilience of the spring arm and the-tension spring operate constantly to causeV the spring arm andthe rear arm ofthe dog lever to lie flatwise against each other for holding the beveled gripping edge of the dog in the path of the temporary barrel hoop. Preparatory to chucking the barrel shell in the chuck rings the head stocks are separated a sufficient distance to permit the barrel'shell .to be placed between the head stocks after which the latter are moved axially toward each other so that the chuck rings surround the ends of the barrelshell and engagefrictionally with the periphery thereof and the beveled edges Vof the several dogs engaged with the outer sidesvof the temporary hoops. As the dogs engage with the temporary hoops the same are deflected' outwardly more or less in adapting themselves to these lhoops `and during thisdeflectionthe deg levers turn more or less so thatI the rear arms thereof are tipped .rela-- tively to the spring tension arms 16 Vand canse the tension -springs l18 v,to loe strained, whereby the dogs are enabled to adapt themselves to the temporaryfhoops and are yieldingly held in engagement therewith so that they firmly gripthevhoopsby slightly indenting the same and insure turning of the barrel shell or body with the chuck rings. Upon separatingthe head stocks from the barrel shell the dogs are disengaged from the hoops 'and again resume their normaly inner position under theaction of their spri-ng arms and tension springs preparatoryto. engag ing with the temporary hoops of the neXt barrel shell.

While the barrel shell is thus arranged between the head stocks preparatory to being chucked thereon and also after the head stocks are withdrawn preparatory to re moving the shell after the work upon the same has been completed the barrel shell is supported betweenV the head stocks by means of twosaddles 19, 19 which may be of any suitable construction and supported upon the adjacent parts of the main frame, for instance, V,by means oftwo bridges and cross pieces 20 arranged transversely between the twohead stocks and resting Iat theiropposite 'ends on the longitudinal-side pieces of the frame, as shown inv Figs l1, 2 and 5. Y V Arranged lengthwise above this frame and parallel with each other are two horizontal supporting bars 21, ,22, preferably of cylindrical form. lUpon these supporting bars are mounted the head stocks by lproviding each of the latter-'on its lower part with front and rear supporting sleeves 23, 24; which embrace the corresponding ends of` the supporting bars. Each ofv these supporting-'bars is mounted at its opposite ends on the main frame so as toJbe capablerof longitudinal movement by means of bearings each of which maybe of anyv suitable construction-but preferably comprises a lower hollow base 25 projecting upwardly from `the' adjacent part of the frame and receiving 27 engaging with the adjacentupper part of said supporting bar Vand connected with the companion base. The supporting wheel is preferably supported by means of an annular row of rollers28 on a horizontal aXle l.

29 which has its opposite ends arranged in vertical slots 8O formed in theinne-r sides of the base and rest with'their und-ersides on the upper ends of vertical adjusting lscrew 31 arrangedin the adjacent upperpart yof the standard. In this manner a rolling antifriction v,support is provided for porting bars which permits of moving the the supf same veasily together lwith the parts mount- ,Y

ed thereon` with a minimum expenditure of labor while ladjusting the machine. The cap 27 is adjustably connected with the standl ard so as to hold the supporting bar properly. in engagement with the wheel 26 and` prevent Jche. parts frombecoming displaced vwhile operating the machine. This adjust` able connection, as shown in Figi 9, prefv erably comprises a horizontal screw (gr-stud 32 mounted on the outer side of the respective base and projecting through a vertical slot 33 in a retaining arm 34 depending ronrthe adjacent part of the cap, a screw nut 35 arranged on the stud and bearing by means of an interposed washer against the outer side of the retaining arm, and an adjusting screw 36 arranged in the lower part of the retaining arm and engaging with the underside of the clamping stud 32. By turning the screws 31 so as to raise the wheel "26 and then turning the screw 36 so as to lower the cap the supporting bar may be adjusted vertically to the required position and held reliably in place for properly operating the machine.

Each of the head stocks is normally rigidly connected with one of the supporting bars so as to move therewith lengthwise of the -machine and is slidably connected with the other supporting bar so that when adjusting the head stocks toward and from` each other the supporting bars slide lengthwise of the machine in opposite directions on the main frame, thereby slidably supporting the head stocks indirectly on the trame and maintaining the same in axial alinement with each other without liability of becoming displaced relatively to each other when the head stocks and the parts mounted thereon are subjected to strains during the operation of the machine. 1n the preferred construction the head stock at the lett end of the machine is secured to the front supporting bar by clamping its tront sleeve on said bar and this head is slidable relatively to the rear supportingbar by mounting the rear sleeve of this head stock loosely on the last mentioned supporting bar.l rEhe front and rear supporting sleeves of the lett head stock are both split lengthwise on diametrically opposite sides of the respective supporting bars and the parts thereof are connected by -means of clamping bolts or screws 37, 38 which may be suitably tightened so that the front sleeve grips 'the front supporting bar for ixedly connecting the left head stock therewith while its rear guide sleeve frictionally engages the rear supporting bar only suliiciently to hold these` parts properly in position relatively to each other but permit the left head stock and rear supporting bar to slide lengthwise one with reference to the other.

The right head stock is preferably connected rigidly with the rear supporting bar so as to be movable vlengthwise therewith by splitting its 'rear supporting sleeve and drawing the sections thereof tightly against sides of this bar by means of clampopposite ing bolts or screws 39, and the right head stock is movable lenofthwise relativel to the front supporting bar by mounting thel front supporting sleeve of this head stock loosely on the `front supporting bar, this last men- -by the following means which tioned sleeve being also split diametrically and the sections thereof connected by means or clamping screws li() so as to hold the right head Stoch properly in frictional engagement with the front supporting bar. By loosening the clamping screw 38 ot the front supporting sleeve of the leit head stoclr and the clamping screw 39 of the rear supporting sleeve of the right head stock, both head stocks may be adjusted axially toward and from each other' in a direction lengthwise of the machine tor adapting the head stocks and the parts mounted thereon to operate on barrels of diiiierent length or height.

The longitudinal movement of the head stocks and associated parts for clicking and releasing a ba rel shell is preferably effected are best shown in Figs. 1, 2, 3, d and 4:1, Li1 represent two substantially hori zontal yolres each of w iich is arranged diametrically across the outer side ot one of the head stocks and pivotally connected at its substantially horizontally opposite ends by means ot radial pivots or bolts i2 with the onter side ot the respective head stock so as to be capable of swinging in a substantially vertical plane relatively thereto. Each of these yolres is provided with a horizontal screw shank-i3 projecting outwardly therefrom in line with the axis of the respective head stock or substantially so. da, t5- represent two upright end rock levers which are pivoted on suitable brackets mounted on the opposite ends of the main frame and each of which is pivctally and adj ustably vconnected at its upper end with the screw shank ot one of the head stock yolres. This connection may be varied but, as shown in Figs.. 1, 2, '-i and 5, the same preferably comprises a sleeve i6 mounted on the respective screw shank and connected on its underside by a horizontal pin 7 with the upper end oi the adjacent end leyeigand screw nuts 48t mounted on the screw shank and engaging with opposite ends oit the sleeve 4G. Upon tightening one of the screw nuts. 48 and loosening the other the respective screw shank 43 may be adjusted relatively to the companion end lever in order to suit the position of the companion head stock on the supporting bars lengthwise ot the machine. Lt9 represents an intermediate upright rock lever which has its upper' and lower arm connected respectively by means of links 50, 51

with the lower arms ot the end lever 41h 45, as shown in4 Fig. 5, so that upon rocking this intermediate lerer in one direction the head stocks will be moved toward each other for chucking a barrel body or shell while upon turning the intermediate lever in the opposite direction the head stocks will be separated for releasing the barrel shell.' For this purpose the intermediate roclr'iever is mounted upon a horizontal roclii siiatt which is journaled transversely in suitable bearings on the lower part of Vthe main `frame and provided at its front end outside of the main frame with a suitable upright operating handle or lever 53 whereby this rock shaft may be turned. This hand lever is preferably adjustably connected with the rock shaft 52 to suit the convenience of the operator and also the length of the barrel which is being operated upon. The preferred means for this purpose consist inproviding the front end of the rockshaft with a cylindrical bearing sleeve 54 which engages with a correspondingly-shaped bearing 55 in the adjacent part of the frame and forms the front support of this shaft, two attaching arms 56 projecting upwardly and downwardly from this bearing sleeve,and engaging with the rear side of the hand lever, and clamping screw or bolts 57 connecting the hand lever and attaching arms 56 and passing through curved slots 58 arranged in this handle arm on opposite sides of the aXisof the rock shaft and concentrically therewith. Upon loosening the clamping bolts or screws 57 the hand lever may be turned vertically as bestA suits the convenience of the operator for chucking a particularlength of barrel after which the hand lever may be secured to the rock shaft 52 by tightening the clamping bolts 57. The downward or forward movement of this hand lever is preferably limited by a stop device which is preferably so constructed that it is adjustable to suit different lengths of barrels.' In its preferred form this stop device consists of a screw 59 secured in an upright position to a bracket 60 on the front part of the main frame anda stop lug 6l arranged on the upper attaching arm 56 and adapted to bear against the upper end of this stop screw. Y j

When the two chuck rings are in engage` ment with opposite ends of the barrel shell 1t 1s desirable to engagethe front sliding sleeveV of the right head stock with the front supporting bar and the rear sleeve of the left head stock with the rear supportingv bar with the maximum pressure de-frived from the weight of the head stocks and the parts mounted thereon for the purpose of holding the same in place during the operation of the machine, but during the time that the operator is vmoving the head .stocks into and out of this operative posij tion it is desirable-to relieve the supporting bars from the pressure ofthe respective head stocks which slide thereon in order to render the operation of chuckingand releasing a shell less laborious andalso reduce the.y wearon the machine. c For this lpurpose a relieving device is provided foreach'head. stock which is preferably constructed as follows: y

62 represents a bracket secured tothe outer v yieldingly held in side of the main frame below the normally slidable supporting sleeve of each head stock and preferably connected with the frame so as to be adjustable lengthwise thereof to suit the position of the 'companion head stock, thisadjustable connection, as shown in Fig. l, preferably consisting of a clamping bolt 63 connecting this bracket and the main frame andl passing through a longitudinal slot'64 in the bracket. On its upper part this bracket is provided with a vertically swinging lifting orsupporting arm 65 which is pivot/ed at one end to. this bracket and is provided adjacent to its pivot formed on the under side of the respective supporting sleeve. This supporting arm is means of a bolt 68 connected at its upper end with a laterally projecting lug 69 formed on the bracket, and a. spring 70 surroundingrthe bolt and bearing at its upper end te the underside of the lug 69 and at its lower end againstl a shoulder on the bolt 68,

. as shown in Fig. l. By turning this bolt 68 the resilienceof this spring be increased or decreased. rThe upward movement of the supporting or lifting arm and roller is preferably limited by means of a stop which may consist of a screw 7l arranged on the lifting arm` and adapted to engage with the underside of the supporting lug 69,asshown in F ig. l. lnpthe retracted inoperative position of the head stocks7 as shown in Fig. 1, the underside of the sliding supporting sleeve of each of these head stocks rests upon the upper side of the lifting roller of the companion friction reducing device, thereby relieving each of lthe supporting bars at this time from the frictional engagement with the lother head stock andenabling the operator to easily effect the initial portion of the movement of Vthe head stocks toward each other. During the last portion of the movement of the head stocks toward each other its 'elevated position by the sliding supporting sleeves clear the lifting rollers 66 vso that the weight of the head sleeves firmly stocks'presses the sliding against the supporting bars and causes these parts to engage each other with a frictional grip which aids Yin retaining the same in ltheir proper relative position. After vthe fil-.5:50

porting bar in the retracted or inoperative position of the head stocks it is possible forshown in Figs. 3, and 6, by means which arev preferably rconstructed as follows: j

72 represent annular gear'rims or gear teeth formed' on the periphery of the chuck rings and engaging with the bottom of the guide groove therein so as to hold these rings centrally within the respective head stocks. 0n vthe underside of each chuck ring its gear teeth are engaged by a driving gear pinion 73 which is confined against axial movement on the respective chuck ring. rlhis' gear pinion is journaled uponv the adjacent part of the companion head stock by journaling the hub 74 of this pinion in a bearing ron the lower part of the respective head stock,v as shownin VFig. l. IFhese driving gear pinions are mounted upon a horizontal driving shaft which is arranged lengthwise in the machine so-that these gear pinions `are capable of sliding on this driving shaft upon adjusting the head stocks towardv and from each other but are compelled to turn with the driving shaft. purpose the driving shaft is provided with a cylindrical portion 76 at the right hand end thereof which is journaled in a stationn ary bearing 77 on the adjacent right end of the main frame, and a portion 78 at the left hand end of the shaft which is preferably square in cross section land' 'engages the corresponding shaped bores in the hubs 'T4 of the driving gear pinions 73, as shown in.

Figs. 5 and 6. By this means a driving connection is established between the driving shaft and the driving pinions which is un.- affected' by the longitudinal movement of the head stock toward and from eachother.

Power may be applied to the driving shaft-in any suitable manner but preferably by means of a driving pulley 7 9 which is adapted to receivel a driving belt and which is mounted loosely on the cylindrical portion of the driving shaft but is capable of axial movement thereon for engaging'the conical bore or clutch face 80 on itsrini with or disengaging the vsame from the clutch shoes Sl arranged on-a clutch disk secured to the adjacent outer end of the driving shaft. Upon pressing the driving pulley axially outward so that its rimV engages with the shoes of the clutch `disk the driving shaft is compelled to turn with the driving pulley but when the outward vpressure on the driving pulley is removed the frictional grip of this pulley on the clutch shoes is released, thereby disconnecting the driv- For thisv ing shaft and driving pulley and permitting the latter to turn while the driving shaft remains at rest. The preferred means for coupling and uncoupling the driving shaft and driving pulley which are shown in Figs. l, Q, il, 5 'and 8 are constructed as follows:

82 representsv an axially movable shifting block slidably mounted upon the cylindrical portion o-f the driving shaft and connected .on one side of the driving shaft with the right end of a shifting rod 83 which is guidedv horizontally and lengthwise in the lower part of rthe main frame. rlhis shifting block and rod when free are moved toward the right by means of a shifting spring 84; surrounding'the shifting rod and bearing at one endk against a collar S5 on this rod and a shoulder formed by the adjacent part of the main' frame whereby the shifting block is pressed against the inner side of the driving pulley and the latter is pushed axially outward and engages its rim with the clutch shoes for coupling the driving pulley and shaft. The shifting block and rod are moved inwardlyso as to relieve the driving pulley from coupling pressure by means of a lower intermediate shifting lever 86 pivoted on the adjacent part of the right end of the main frame so as to swing` in a substantially horizontal plane and provided at its rear arm with a fork 87 which embraces a shifting collar SS on the shifting rod, and a vertically swinging controlT ling lever 89 pivoted on the adjacent part ofthe right end of the mainframe and provided with a depending cam 90 which engages with a roller 91 on the front arm ofthe shifting lever VS6. When the controlling lever is turnedV into its rearmost 'posi'- tion, as shown in F ig. 4:, the cam 90 is in its foremost position and turns the shifting lever so as to cause the shifting rod to be retracted to the left and the outward pressure on the driving pulley to be relieved, whereby the latter is uncoupled from the driving shaft and the operation of the machine arrested. Vhen, however, the controlling'lever is turned intoits forward'position and its cam 90 is moved rearwardly the shifting lever is released and the spring Sil is permitted to shift the rod S3 and block 82 outwardly lengthwise of the driving shaft for coupling the driving pulley with this shaft and .causing the machine to operate.

The turning of the controlling lever in the direction for uncoupling the driving pulley and shaft is preferably arrested by a stop device which is adjustable and which preferably comprises a stop screw 92 arranged 'in a lug 93 `on the right end of the frame in position to be engaged by a stop lug 9e arranged on the hub of the controlling lever7 as shown in Figs. l and 4.

. In order to cause therotation of the driving shaft to be arrested immediately upon disconnecting the same from the driving pulley a brake mechanism is provided which preferably comprises an elbow lever 96 pivoted on the right hand end of the main frame and having an inwardly projecting 'arm which is provided with a fork 97 engaging with a lug 98 onthe shifting block, anda horizontally projecting arm provided with a'brake shoe 99 arrangedy opposite the face of an annular brake iiange 100 formed on the clutch di'sk. Upon moving the shifting block inwardly or awayl from the driving pulley the brake lever 96 isV turned in the direction for engaging the brake shoe with a brake fiange of the clutch disk, thereby arresting the rotation of the driving shaft and the parts operatively connected therewith. l/Vhen, however, the shifting t block is moved outwardly for causing the driving pulley to couple with the driving shaft then the brake lever is turned in theA opposite direction and the brakeshoe is moved away from the brake flange so that the driving shaft and associated parts` are free to turn. n The cutter mechanism whereby the howels, crozes, chamfers, ridge faces and end faces are produced on the staves of the barrel isv constructed and operatedV as follows 101, 101 represent two inain'cutterV levers which are arranged in anfupright posit-ion adjacent to the outer sides of the head stocks and each of which is pivoted at its lower.

end to the lower part of the respective head Y stock by means of a horizontal'longitudinal bolt 102 so thatthis cutter leverv can swing in a vertical plane crosswise of theaX'isof the respective chuck ring and head stock.l

' In order to prevent the freecutter levers the blades, knives or cutters for producing the croze, howel, chamfer and ridge face at one end of the staves of the barrel shell. As shown in Figs. 3, el., 5, 6 and 1 0, 104C represents the cutter which producesthe croze,

105 the cutter which produces the howel, 10G theV cutter which produces the chamfer and 107 the cutter which produces the ridge face at one end of the staves of the barrel body or shell.v In the chucked 'position of the barrel shell on the ychuck rings each set of croz'e, howel, chamfer and ridge face cutters or blades is arranged withink the barrel shell adjacent to onel endV thereof and these ,cutters or knives are so mounted upon the companion cutter' lever that upon swinging the latter outwardly these cutters will be engaged with the end portion of the staves on the inner ysides thereof for producingthe above described` operation on the lstaves. Various means may be provided for adjustably supporting these 4blades on this cutter lever so that they may be presented to the staves in the best position for doing their work and also tok permit of taking up wear when these cutters become worn. As shown in V.the drawings these several .blades are preferablymounted adjustably on the head 108 of a tool holder which head is provided with a horizontal cylindrical shank 109 journaled in a horizontal bearing on the adja cent main cutter lever so that the, tool' head and the cutters mounted thereon are arranged on the inner side of the maincutterV lever. The tool holder may be turned in a vertical plane for presenting the cutters or blades thereon in the most favorable position lto the staves. The preferred means for this purposewhich are shown inFigs. 3, 4L and 5 comprising an adjusting arm 110 secured tov the outer end of the tool holder shank and adjustably connected with the adjacent part of the'iespective cutter lever by means of a clampingV screw or bolt 111 passing through a curved slot 112 in the adjust.- ing arm. Upon loosening the clamping bolt the tool holder may be rocked about the axis of the shank 109 to the desiredfposition and then held in place by again-tightening this clamping screw. In the inoperative position of the several cutters. which are.

mounted on the toolholder the main cutter lever extends in a substantially diametrical position across the companion head stock 'and chuck ring in which position these cut'- ters are retracted out of the,l path of thev staves'and are in their inoperativey position. Upon swinging the cutter lever laterally'outward transversely of the axis of the barrel, chuck ring and head stock the cutters mounted on the main cutter leverv are cngaged with the inner sides of the end portions of the staves andproduce the various operations thereon corresponding to these cutters. The means. whereby vthe two" main cutter levers are thus moved transversely into landout oftheir operative positions is effected bythe movement of the controlling.

leverupon connecting and disconnecting the driving pulley and-driving shaft. The preferredmeans for thispurpose is best shown in Figs. 1-6 andlQ and constructed as follows: p Y

`113 represents a longitudinal operating or controlling shaft whichrispreferably square in cross section and arranged lengthwise between the underside of thek head stocks and the upper part of the main frame. To the right hand end of this shaft is secured .the operating or controlling lever 89 andthe cam 'arm 90, as shown in Figs. 1,2, d and 12.

l116,117in the lower parts of the right and left head stocks and each of which is provided with an axial opening of square cross section which receives the operating shaft 113 so that these sleeves are compelled to turn with this shaft but are free to turn thereon. The right bearing sleeve 1111 is provided at its inner end with an enlargement or collar 118 which bears against the inner side of the right hand head stock while its opposite end has secured thereto the hub 119., of a lower toggle arm 120 which hub bears against the outer side of the right head stock, thereby holding the bearing sleeve 114e against axial movement on this head stock. l1`he lower toggle arm is connected with the central part of the right main cutter ever by means of a toggle link which preferably comprises an upper screw shank 121v pivotally connected with the respective cutter lever, a lower screw shank 122 pivotally connected with the respective toggle arm and an adjusting sleeve 123 having right and left hand screw threads whereby the same is connected with the upper and lower screw Shanks. Upon turning the operating shaft 113 so that the toggle arm is in a substantially horizontal position and the pivotal connection between the same and the toggle link on one side of a line extending from the axis of the operatingshaft to the pivotal connection between the toggle link and the companion cutter lever, the'latter and the parts mounted thereon will assume the positionindicated in Fig. L1, in which position the ,cutters o-n this lever are retracted into their inoperative position. Upon turning the operating shaft 113 so, as to bring the pivotal connection between the toggle arm and toggle link on the dead center line eX- tending from the axis of the operating shaft to the upper pivot of the toggle link, ,as shown in Fig. 13, the respective cutter lever will be swung outwardly and bring the cutters mounted thereon intoengagement with the staves of the barrel shell. rl`he position of these cutters relatively to the barrel staves may be adjusted by turning the adjusting sleeve 123 of the toggle link in one direction or the other by means of a wrench applied to the hexagonal central part of this sleeve, as shown in Fig. el, andl thereby either shorten or lengthen this toggle link as required. 1n order to arrest the movement of the toggle arm and toggle link when these parts have been turned into a position inwhich the pivotal connection between the same is on the dead center or in line with the aXis of the operating shaft and the upper pivot of the toggle link a stop device is provided which preferably comprises a stop lug 121 arranged on the lower screw shank below the pivotal connection between the same and the toggle arm and engaging with a. stop lug 125 formed on the opposing part of the hub of the companion toggle arm, as shown in Fig. 12, thereby avoiding throwing the toggle arm and toggle link past the dead center and .holding the same in a locked position relatively to each other and effectually supporting the cutter lever while its cutters or blades are engaging the barrel staves.

The bearing sleeve 115 which is journaled in the left head stock is provided with a collar 126 at its inner end which bears against the inner side of this head stock and on the outer part of this bearing sleeve is 'inoiuited the hub 127 of a lower toggle arm 123 which' bears against the outer side of the left head stock7 as shown in Fig. 11. This last mentioned toggle arm is connected withfthe left main cutter lever by means of I a toggle link comprising upper and lower screw shanks 129, 130 which arepivotally connected respectively with this left cutter lever and the left toggle arm, and an adjusting sleeve 131 having right and left handr screw threads engaging with the corresponding threads of the upper and lower screw shanks 129, 130, so that upon turning this sleeve by means of .a wrench applied to the hexagonal center part of the same this toggle link may be lengthened or shortened. The toggle arm and link associated with the left main cutter lever operate simultaneously with the toggle arm and link associated with the right main cutter lever and in the saine manner described with reference to the rig it main cutter lever so that both of these cutter levers are moved in unison for engaging their cutters with the barrel staves and disengaging the same therefrom upon turning the operating shaft 113 in one direction or the other byI means of the operating lever. The right toggle arm is prefereably connected permanently with its bearing sleeve 111 so that when the operating shaft and operating lever are rocked the right hand cutter lever is always moved for engaging or disengaging the cutters mounted thereon with the barrel stavcs. The left toggle arm is however preferably provided with means whereby the samemay be either connected with its companion bearing sleeve 115 or disconnected therefrom in order to permit of moving both of the cutter levers into and out of their operative position when it is desiredito out both .ends of the staves of the shell at the same time or the left cutter lever may be vdisconnected from the operating shaft and rendered inoperative so that upon rockingthis shaft only the right cutter lever will be moved into and out of its operative position forcutting the staves only at the right hand end of the barrel shell. The purpose of thus disconnecting one of the cutter levers fromv the shifting mechanism is to enable the cooper when he disc-overs a defected stave in the barrel shell to cut only one end of the staves in the shell, then replace the broken stave by a good one, after which the simultaneous cutting ofl both ends of the staves in the barrel shell maybe resumed and completed simultaneously. 1n making such repairsit is customary to have a lot of staves on hand which have one end cut with the appropriate croze, chamfer and howel so as to permit of readily assembling the saine with the remaining staves in the barrel which is being repaired preparatory to-completing the cutting of both ends of the staves.

Various means may be provided for con-A necting and disconnecting the left' main cut ter lever with the operating shaft, those shown in Figs. 1, 2, 3 and 11 being preferred and comprising a clutch sleeve 132 splined on'the Outer end of the bearing sleeve 115 and provided on its inner end with clutch teeth 133 which are adapted to engage with clutch teeth 134 on the outer end of the.

`hub of the lefttoggle arm. When the clutch sleeve 132 is moved inwardly so that its teeth 'interlock with those of the adjacent toggle arm the toggle mechanism of both cutter levers are in operation and both sets of cutters on these levers. are moved into and out oftheir operative `position upon rocking the operating shaft. When, however, the clutch sleeve 132 is withdrawn axially so that its teeth are disengaged from those of the adjacent toggle arm the rocking movement of the operating shaft does not shift the left main cutter lever into its operative position but only moves the right cutter lever into its operative position for cutting the corresponding ends of the barrel staves.r The clutch sleeve 132 may be moved into and out of its operative position by. any suitable means, forinstance, by a hand lever 135 mounted on the outer side of the left head stock and engaging with the clutch sleeve 132, as shown in Figs. 2 and 3. In order to prevent the left toggle arm from dropping out of place when the same is disconnected from the companion bearing sleeve a stop device is provided which preferably comprises a stop screw 136 arranged in a lug 137 projecting inwardly from the left toggle arm and bearing against an adjacent relatively, stationary part of the machine, for instance, the cap of the bearing in which the hub of the left hand driving gear pinion is journaled. Upon sliding the head stocks lengthwise of the machine the bearing sleeves 114, 115 of the togglepmechanism slide upon operative connection between the operating position for trimming 0E the-ends of the` staves during the rotation ofthe barrel shell. These f end trimming Vcutters arek v arranged along the outer sides of the right and left head stocks, respectively, and are adapted to move inwardly across the end portions of the staves for-trimming the ends thereof. Each ofthese end trimming cutters is mount-l ed on the upper arm of an auxiliary rock lever 139 which is pivo'ted to turn in a vertical position adjacent to the respective head stock. The auxiliary cutter lever is normally held by gravity in a posit-ion in which its cutter is out of the path of the barrel staves, by reason of the overhang of the upper armof this cutter and the parts mounted thereon. The forward or operative move# ment of this cutter levery is lproduced by means of a tappet 140 arranged on the lowerl part of the'main cutter lever'and engaging with a roller v141 mounted in an opening in the lower arm of the auxiliary cutter lever. This tappetis preferably curved concentrically with the axis of the respective main cutter lever and is adjustable in a circumferential direction relatively thereto by means of a clamping screw 142 mounted on the respective main cutter lever and engag-v ing with the side ofthe tappet, thereby enabling the parts to be timed relatively to each other'so that the end trimming cutter performs its function properly. In order to enable each auxiliary cutter lever to be adjusted bodily transversely of the respective headl stock to suit the barrel shell which is being cut this lever is pivotally mounted on a slide 143 which is guided in a radial way the next part of this movement of the operating lever the cutters are moved into their operative position, thereby 4starting the rotation of the barrel shell before the same is engaged by the cutters. y

Y In order to still further hold the two head stocks firmly against displacement relatively to each otherA during thecutting operation iro means are provided 'whereby one of the head stocks is firmly clamped to the supporting bar upon which the 'same slides into and out of its operative position. As shown in Figs. 1, 2, 4 and 7, this 'clamping mechanism is arranged to connect the iront sleeve of the righthead stock with the front supporting bar during the operation of moving the cutters into their operative position. This auX- ilfilary clamping mechanism comprises va clamping block 147' adapted to engage with the underside of the front supportingbar and movable vertically in a guide opening MS in the underside ofthe front supporting sleeve of the right f head stock, van inner clamping` lever 1419-pivote'd on the lower part ot' the right front supporting sleeve and provided with afscrew 150 which bears against the underside of the clamping block, an in*- termediate clamping lever 151 pivot-'ed =on the 4lower part of rthe right front supporting 'sleevel and engaging its inner arm with the underside of the inner clamping lever, a shifting rod 153 `pivoted on the right toggle arm jand passing loosely through an opening 154 in the 'upper arm of the intermediate clamping lever 151, and a spring 155 surroundin-g the shifting rod 153 and bearing at one end against a collar 15:6 on this rod and at its other 'end 'against the inner side of the upper arm of the intermediate clamp'- ing lever, as best shown inl Fig. 7. Upon turning the operating sha-ft in the direction for moving the'cutters into ytheir voperative position the adjacent toggle at the same time moves upwardly and outwardly so Vas to press thespring 155 against the intermediate clamping lever from which latter the motion is in turn transmitted to the inner clamping lever, whereby the ciampi-ng blocl is pressed against the underside of the front support-v ing bar and the left head stock is firmly locked on this bar, thereby aiding in holding the two head stocks against displacement relatively to each other and securely gripping the barrel shell between the two chuck rings so as to insure proper cutting 'of the same. Upon turning the operating shaft in the opp'osite direction for disengaging the cutters from the barrel staves the respective toggle arm swings inwardly and downwardly so as to release the pressure on the spring 155 and thereby relieve the O'rip of the clamping block 1117 against the front supporting bar.

When adjusting' the cutters for cutting a particular barrel shell it is desirable to move the cutters toward and from the barrel shell without turning the latter. In order to permit of this, means are provided whereby the shifting block 82 and shifting rod SB are held in theirinoper'ative position while the operating lever is turned lin a direction for lmoving the main and auxiliary 'cutter levers intotheir operative position relatively to the barrel staves. rl`he preferred means for this ypurpose which are shown in the drawings comprise a tappet 157 secured to the shifting rod 83 adjacent to its right hand end,and a vertically swinging cam lever 158 in'ounted on the right end of the main frame and provided on its rear arm with a cam 159 adapted to engage with the tappet 4157. Upon turning this cam lever so that its -`c-am enga-ges with the tappet of the shifting rod the latter will be shifted into its retracted position and held there, together with the shit-ting block, thereby preventing the spring S4 from moving the shifting rod 'and block in a direction which would cause the driving pulley to be connected with the 'driving shaft, notwithstanding that the operating lever 89 is turned in a direction for moving the cutters into the path of the barrel stavesat which time the cam 90 on the `operating lever presents its low face lto the Aroller on the front arm of the intermediate rock lever 86 which ordinarily would per- -mit the spring 84 to couple the driving clutch and causethe barrel rotating` mechanism to operate. l This 'machine is very durable in const-ruction, the same 'is easily adjusted and controlled, and it permits of cutting barrels eX- p'ediitio'usly, reliably and economically.
